Subject: mm/damon/sysfs-schemes: use nr_accesses_bp as the source of tried_regions/<N>/nr_accesses
Date: Sat, 16 Sep 2023 02:09:38 +0000
DAMON sysfs interface exposes access rate of each region via DAMOS tried
regions directory. For this, the nr_accesses field of the region is used.
DAMOS was actually using nr_accesses in the past, but it uses
nr_accesses_bp now. Use the value that it is really using as the source.
Note that this doesn't expose nr_accesses_bp as is (in basis point), but
after converting it to the natural number by dividing the value by 10,000.
Hence there is no behavioral change from users' perspective.
